Abstract
Abstract A capacitor winding machine includes a first core loading and winding position for winding a predetermined number of turns of two metallized films onto the core prior to moving the winding to a second finishing and ejecting position. Once the predetermined number of windings have been applied to the core in the first position, the winding is moved with the films under tension between the core and their respective supply rolls to the second position and the films are attached to and terminated from a second core which has then been loaded into the first loading position. The first core is then rotated to wind the free ends of the film onto the core which may then be heat or otherwise sealed to complete the metallized plastic film capacitor prior to being ejected from the machine.
